解開吊索
英文
unsling-
There are many materials and members to be hoisted during construction of the suspension bridge, unfortunately, the out - spread overhead curved cable makes it impossible for hoisting the stiffening girder with normal cable - supported lift. in order to ensure the construction proceeded smoothly, a multifunctional overhead cableway system is developed, thus accommodating all the hoisting tasks for the superstructure ( stiffening girder )
懸索橋施工中需要吊裝的材料和構件很多，豐都長江大橋懸索橋主纜採用空間外張式，使加勁梁的吊裝不能採用一般的纜載吊機形式，為使施工的順利進行，本橋施工中開發了多功能高架索道施工方案，以一副索道完成了多種工作，全面解決了上部結構（包括加勁梁）的多項吊裝作業。To avoid the probability, engineer calculate the cable tension and the pre - rising elevation with finite element theory, it cost much time in design the program and repeat calculation, the other hard work is to find out the place where the cables located in span arch structure, its must find out the optimized result manually which restrict the design work. recent years, lots of commercial fea software develop rapidly. engineers focus on the solution of commonness problems by the software existed
為了解決這個問題，設計人員常常採用有限元方法計算扣索受力及拱肋控制標高，並根據計算結果設計扣索吊裝位置，在此過程中大量重復編程及計算工作佔用了很多工作時間，另外在扣索吊裝位置的選定過程中又沒有明確的方法，只能根據大量的計算結果人工尋找優化方案，這些都制約著設計工作的開展。
